form.h (struct form_control): renamed caret_char_offset to caret_box_offset; Added caret_form_offset & length.
form.c: initialise new entries in struct form_control; form_successful_controls() : code reshuffling to improve readibility.
box.h: TABing.
box.c (box_input): init struct form_control::length.
browser.c (browser_window_input_callback): UTF-8 support. Text area code needs similar changes.
